PY - 2004/12/1. Y1 - 2004/12/1. N2 - Purpose: To retrospectively review 8 years experience with stent-graft treatment of aortic dissections at a single institution. Methods: Forty-six patients (31 men; mean age 59 years, range 38-88) underwent stent-graft treatment for 9 Stanford type A and 37 type B aortic dissections (9 acute phase, 13 subacute, 24 chronic). Custom-designed self-expanding stainless steel Z stents covered with polytetrafluoroethylene were used (n=20) until low-profile modular stent-grafts became available for percutaneous delivery (n=26). Results: Endovascular stent-graft deployment was technically successful in 44 (96%) patients; the 2 failed cases owing to intraprocedural migration and graft torsion were converted to surgery. There were 5 type I endoleaks for a clinical success ...
December 6, 2016 -- Dublin -- Medtronic plc (NYSE:MDT) today announced that it has received CE (Conformité Européenne) Mark for the Endurant™ II/IIs stent graft system to treat abdominal aortic aneurysm (AAA) patients using a ChEVAR procedure, a parallel graft chimney technique that uses commercially available balloon expandable covered stents combined with a standard aortic stent graft. This expanded indication in the European Union enables the Endurant II/IIs stent graft system to be used in patients with complex aneurysms with short aortic neck lengths ,2 mm, expanded from the prior neck length indication ,10 mm. Treating aneurysm patients with short aortic necks has been a long-time challenge for clinicians performing endovascular aneurysm repair (EVAR) to treat AAA patients, said Professor Giovanni B. Torsello, M.D., chief of Vascular Surgery, St. Franzkisus Hospital, M?nster, Germany and co-author of the PROTAGORAS study. The availability of a standardized approach which increases ...
October 23, 2018 -- Dublin -- Medtronic plc (NYSE:MDT) today announced it has received U.S. Food and Drug Administration (FDA) approval for the Valiant Navion thoracic stent graft system for the minimally invasive repair of all lesions of the descending thoracic aorta, including thoracic aortic aneurysms (TAA), blunt thoracic aortic injuries (BTAI), penetrating atherosclerotic ulcers (PAU), intramural hematomas (IMH), and aortic type B dissections (TBAD). Until now, patients with small iliac arteries were considered ineligible for thoracic endovascular aneurysm repair (TEVAR) or required adjunctive procedures to accommodate calcification and tortuosity concerns. Valiant Navion allows for the potential for more patients to receive a percutaneous procedure and overcome these anatomical concerns, enabling a less invasive approach to treatment compared to surgical cut-down (open) procedures. Our focus at Medtronic continues to be on advancing the treatment of complex aortic disease to improve ...

September 28, 2017-The US Food and Drug Administration (FDA) has issued a letter to health care providers advising that the agency is evaluating recent information regarding type IIIa and IIIb endoleaks with the use of endovascular graft systems indicated for endovascular aneurysm repair (EVAR) procedures. The letter, addressed to vascular and cardiothoracic surgeons, radiologists, and cardiologists, stated that an increase in the occurrence of type III endoleaks has been suggested by several sources, including the FDAs Medical Device Reporting system and the Annual Clinical Updates to Physicians by the manufacturers. This increase is compared with earlier clinical update reports in patients with various device models and implant duration lengths, including some patients who had previously stable repairs.. The purpose of the FDAs letter is to bring this potential complication to the attention of health care providers and to remind and encourage them to report type IIIa and IIIb endoleak events ...
Fenestrated and branched endovascular aortic repair (F/B-EVAR) is associated with a high degree of technical and clinical success. Despite this, studies have also reported high reintervention rates, and these are often related to the bridging stent grafts. Often new devices appear on the market before they have been tested in the bridging stent graft position. This review aims to assess the current literature on bridging stent grafts and discuss complications, illustrated by case reports. Complications reported with bridging stent grafts include; endoleak, kink, fracture, migration, occlusion, stenosis and perforation. Some known risk factors for bridging stent occlusions are renal artery stent grafts vs. SMA and celiac artery stent grafts. Some device specific complications have also been reported such as type IIIc endoleak with the Lifestream stent graft (Bard Peripheral Vascular, Tempe, AZ, USA) fractures and type IIId endoleaks with the 1st generation of Begraft (BentleyInnoMed, Hechingen, ...
Instead of open aneurysm repair, your vascular surgeon may consider a newer procedure called an endovascular stent graft. Endovascular means that the treatment is performed inside your artery using long, thin tubes called catheters that are threaded through your blood vessels. This procedure is less invasive, meaning that your surgeon will usually need to make only small incisions in your groin area through which to thread the catheters. During the procedure, your surgeon will use live x-ray pictures viewed on a video screen to guide a fabric and metal tube, called an endovascular stent graft (or endograft), to the site of the aneurysm. Like the graft in open surgery, the endovascular stent graft also strengthens the aorta. Your recovery time for endovascular stent grafting is usually shorter than for the open surgery, and your hospital stay may be reduced to 2 to 3 days. However, this procedure requires more frequent follow-up visits with imaging procedures, usually CT scans, after endograft ...
OBJECTIVE This study reports the early and midterm to long-term experience of chimney grafts (CGs) in urgent endovascular repair of complex lesions in the thoracic aorta. METHODS Twenty-nine high-risk patients (20 men) who were unfit for open repair were treated using CG technique for ruptured (n = 14) or symptomatic (n = 15) aortic lesions engaging the aortic arch itself (n = 9), the descending aorta (n = 10), or the thoracoabdominal aorta (n = 10). Twenty-two patients (76%) were treated urgently (≤24 hours) and seven were semiurgent (≤3 days). Of 41 chimneys used, 24 were placed in supra-aortic branches and 17 in visceral branches. Median follow-up (interquartile range) for the entire cohort was 2 years (0.6-3.8 years), 2.5 years (1-4 years) for 30-day survivors, and 3.5 years (1.9-6.4 years) for those who were still alive. RESULTS Four patients (14%) died ≤30 days of cerebral infarction (n = 1), visceral ischemia secondary to the initial rupture (n = 1), multiple organ failure (n = 1), or
Dr. Courtney M. Townsend, Jr. (right), President of the American College of Surgeons, presents Dr. Timothy A.M. Chuter (left) with the 2017 Jacobson Innovation Award. Between 1993 and 2000, there was rapid expansion in the scope of endovascular aneurysm repair including the first endovascular repair of a ruptured aortic aneurysm (1994), the first endovascular repair of an aortobronchial fistula (1995), the first bifurcated stent grafts (1993), the first inflammatory aneurysms (1995), the first fenestrated stent grafts for aneurysms of the pararenal aorta (1998), and the first branched stent grafts for the thoracoabdominal aorta (2000). Although none was the work of a single inventor, Dr. Chuters trailblazing work was pivotal in this rarefied period of surgical breakthroughs, not simply by his invention of new forms of endovascular aneurysm repair, but also through his mentoring of surgical residents, fellows, and faculty. Notably, Dr. Chuter has nurtured his inventions from conceptualization to ...
AccessGUDID - Fluency® Endovascular Stent Graft (04049519008639)- FLUENCY® PLUS Endovascular Stent Graft 12 mm x 40 mm (80 cm delivery system)
different portions of the stent/stent graft 10 are heat set at different diameters. For example, a braided material could be fabricated on a mandrel having a first larger diameter (e.g., 30-35 mm), which is generally the maximum diameter to which the stent/stent graft would be capable of expanding. The braided material may then be pulled down or compressed onto a mandrel having a second smaller diameter (e.g., 20-25 mm) and heat set such that the heat set stent/stent graft is capable of self-expanding to the diameter of the second smaller diameter. However, when the stent/stent graft 10 is axially compressed, the stent/stent graft is capable of expanding to the first larger diameter. Thus, in order to deploy the stent/stent graft 10, the distal end 34 of the stent/stent graft 10 may be positioned distally of the aneurysm 14 and as the delivery catheter 38 is retracted, the distal end of the stent/stent graft engages the lumen 12. As the stent/stent graft is further deployed in the region of an ...
Medtronic Receives FDA Breakthrough Device Designation for Developing Stent Graft System to Treat Thoracoabdominal Aortic Aneurysm - - Minneapolis (Minnesota)
In this issue of the Journal, Howell et al. (1)present some tuly remarkable results. Working in an interventional cardiology suite, they were able to implant the Medtronic AneuRx stent graft in all but one of 215 patients. Most of these patients had major comorbidity with an American Society of Anesthesiologists grade of IV or higher in 58.6% of patients. All these sick patients underwent stent-graft implantation under general anesthesia, yet only one patient suffered a non-Q-wave myocardial infarction, none died in the perioperative period, and most went home the next day.. One notable aspect of the technique described by Howell et al. (1)is the use of the Prostar XL device to facilitate percutaneous arterial closure. The 16F contralateral access site was closed this way in 174 of 188 attempts, and the 22F ipsilateral access site was closed in 26 of 27 attempts. Few centers have achieved such a high rate of success with percutaneous arterial insertion of large-bore sheaths. Indeed, one wonders, ...

TY - JOUR. T1 - Devices for endovascular abdominal aortic aneurysm repair. AU - Lipsitz, E.. AU - Veith, F. J.. AU - Ohki, T.. PY - 2001/5/22. Y1 - 2001/5/22. N2 - Abdominal aortic aneurysms (AAAs) are a significant cause of morbidity and mortality worldwide whose incidence is increasing. Traditionally these aneurysms have been repaired by a standard surgical approach. Over the past decade, spurred by the development of endovascular therapies for a variety of vascular pathologies, the endoluminal treatment of AAAs has rapidly proliferated. Early stent-grafts used to treat AAAs were primarily home-made. Presently there are a number of industry-made devices available on both an investigational and approved for use basis and the number is growing. This review focuses on the types of stent-grafts currently available, indications for use and patient selection, as well as new patents issued over the years 1998 - 2000. The ideal stent-graft is yet to be developed and not all AAAs are amenable to ...

Abdominal aortic aneurysm repair has undergone a revolution since Volodos and Parodi described endoluminal repair in the early 1990s. Subsequent data from large registries have confirmed its efficacy. Randomised controlled trials have shown that although endoluminal repair may not be as cost effective as open repair, it can be performed with a lower mortality in patients fit for open repair. Some European countries (eg, Belgium) have taken the results of these trials to rationalise the number of hospitals able to do endovascular repair. The devices continue to improve and although most require open surgical access at present, in future percutaneous access will become the norm. This article reviews the current state of endoluminal aortic aneurysm repair in the infrarenal aorta. ...

First generation aortic endovascular stent-grafts (EVG) had low applicability and were associated with a significant incidence of peri-procedural complications. With time, a number of EVG systems perished (some predictably) in a survival of the fittest. Improvements in design have been made as a result of these failures. Current designs have low peri-procedural morbidity and mortality and improving durability. This paper sets out to discuss the use of a variety of EVG for abdominal aortic aneurysm repair. The ideal properties of an EVG will be outlined along with some of the advantages and limitations of current, and, where appropriate, historical, commercially available stent-graft systems.. ...

RnRMarketResearch.com adds MediPoint: Aortic Stent Grafts - APAC Analysis and Market Forecasts to its store.. Aortic stent grafts are most commonly used to reinforce a weak spot in an artery, which is known as an aneurysm. The stent grafts are designed to seal tightly with the patients native artery above and below the aneurysm, and are used to treat abdominal aortic aneurysms as well as thoracic aortic aneurysms. Aortic aneurysms, as opposed to aneurysms found elsewhere in the body, are potentially very serious, as a burst aorta results in massive internal bleeding that can be fatal unless treated rapidly by an experienced emergency medical team. Since their introduction in patients in 1991, aortic stent graft devices have gained wide acceptance and availability, with their adoption fueled in great part by advances in stent-graft design and by a variety of devices for various anatomic features. Over time, these devices have gained traction for use in patients with ruptured aneurysms because ...

OBJECTIVE: To assess whether a strategy of endovascular repair (if aortic morphology is suitable, open repair if not) versus open repair reduces early mortality for patients with suspected ruptured abdominal aortic aneurysm. DESIGN: Randomised controlled trial. SETTING: 30 vascular centres (29 UK, 1 Canadian), 2009-13. PARTICIPANTS: 613 eligible patients (480 men) with a clinical diagnosis of ruptured aneurysm. INTERVENTIONS: 316 patients were randomised to the endovascular strategy (275 confirmed ruptures, 174 anatomically suitable for endovascular repair) and 297 to open repair (261 confirmed ruptures). MAIN OUTCOME MEASURES: 30 day mortality, with 24 hour and in-hospital mortality, costs, and time and place of discharge as secondary outcomes. RESULTS: 30 day mortality was 35.4% (112/316) in the endovascular strategy group and 37.4% (111/297) in the open repair group: odds ratio 0.92 (95% confidence interval 0.66 to 1.28; P=0.62); odds ratio after adjustment for age, sex, and Hardman index 0.94 (0.67
Boomington, Ind. ─ Cook Medical has received premarket approval from the U.S. Food and Drug Administration (FDA) for its lower-profile Zenith Alpha™ Thoracic Endovascular Graft. Zenith Alpha Thoracic is indicated for the endovascular treatment of patients with isolated lesions of the descending thoracic aorta (not including dissections) having vascular anatomy suitable for endovascular repair1.

Some abdominal aortic aneurysms can be repaired using endovascular stent grafting. Medtronic AneuRx AAAdvantage and Talent Abdominal Stent Grafts are used for this procedure.
An endovascular stent graft is placed inside the abdominal aortic aneurysm to help prevent rupture. Medtronic is a leading developer of endovascular stent grafts.
Aneurysms of thoracic aorta and abdominal aorta are rare and their treatment traditionally involved complex surgical repair with attendant morbidity and mortality. Nowadays, interventional non-surgical management with Endovascular grafting using covered stent grafts (EVAR : Endovascular Aneurysm Repair) has become the treatment of choice in the majority of cases. This is the tale of a 67 year old hypertensive gentleman with Coronary artery Disease presenting with very large saccular Aneurysm in
OBJECTIVE: The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS: Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for endovascular treatment was evaluated by computed tomography scanning and anatomical features were determined based on the method of treatment. RESULTS: From February 2012 to January 2013 (12 months), 28 consecutive patients (mean age 67.2 years, range 45-85 years) underwent treatment for ruptured abdominal aortic aneurysms at our hospital. Eighteen patients (64.3%) were suitable for and underwent endovascular treatment with bifurcated endografts (16 patients) or aortouniiliac endografts (two patients). Ten patients who were considered unsuitable for endograft repair underwent open repair. Seven patients were ...

TY - JOUR. T1 - Endovascular management of abdominal aortic aneurysms. AU - Bush, R. L.. AU - Lin, P. H.. AU - Lumsden, Alan B.. PY - 2003/8/1. Y1 - 2003/8/1. N2 - An estimated 1.5 million people in the United States haves abdominal aortic aneurysms (AAAs) with more than 200 000 American diagnosed each year. The natural history of AAAs is to expand and rupture, accounting for an estimated 15 000 deaths per year. Thus, the major impetus for AAA repair is for prophylaxis against aneurysm-related death. The standard open surgical repair of AAAs is a well-established and durable procedure. However, as with all other major abdominal surgical operations, associated significant morbidity and mortality exist, along with prolonged recovery and various late complications. Furthermore, both mortality and morbidity increase significantly with advanced patient age and associated co-morbid disease states. Endovascular AAA repair using covered stent-grafts offers a significantly less invasive alternative to ...

Aortic aneurysm repair requires only a small incision in your artery. The surgeon will usually access your femoral artery, which is a branch of the aorta, by making a small incision in another part of your body, such as your groin. He or she will first insert a wire through the incision and into your femoral artery. The wire will help guide a long thin tube, called a catheter, through the inside of the arteries to the place of the aneurysm. The catheter can safely navigate through the inside of arteries; it reduces the risk of the procedure, allows for a quicker recovery , and reduces pain. Your arteries have no nerve endings so you should not feel any pain as the wire moves through them. The surgeon guides the catheter to the aneurysm and puts the stent graft into place to repair the weakness. Some stents slowly release medications to help prevent blood clots and other problems after the procedure. After the stent is securely in place, the surgeon removes the catheter, closes the incision ...

N2 - Five patients with pseudoaneurysms of the carotid artery (n = 4) and an arteriovenous fistula of the vertebral artery (n = 1) were treated with stent-grafts. Commercially made devices were used in all but one of the patients. In four of the five patients, the pathology was successfully excluded. One patient had a small type-I endoleak. There were no immediate procedure-related complications or neurologic sequalae. All experienced immediate resolution of symptoms. One patient was lost to follow-up after discharge and another died 2 weeks after intervention. The remaining patients remained asymptomatic with patent stent-grafts after follow-up periods of 14, 16, and 46 months, respectively.. AB - Five patients with pseudoaneurysms of the ...
Endovascular repair of complex aneurysms involving the visceral arteries has become a reality. Fenestrated endovascular aortic repair (FEVAR) has been used with increasing frequency to treat complex aortic aneurysms. The Zenith fenestrated stent-graft system (Cook Medical Inc, Brisbane, Australia) was approved for commercial use in the United States in April 2012, offering a custom-made design with up to 3 fenestrations to treat short-neck infrarenal and juxtarenal abdominal aortic aneurysms. Nevertheless, FEVAR is a complex procedure that demands accurate planning, advanced endovascular skills, and excellent perioperative patient care to achieve optimal outcomes ...
The invention provides an endovascular graft system for repair of aneurysms. The graft system includes a trunk component and first and second leg components. The graft components include graft material supported by a plurality of stents which are spaced apart and affixed to the graft material in a manner that allows articulation of the graft system without excessive wear of the graft material. The stents are formed by intersecting struts which may be tapered to relieve stress. A stabilizing mechanism is provided to stabilize the position of the legs with respect to the trunk when the graft system is deployed.

SCVS 2018 Abstracts: Statin Therapy is Associated with Higher Long-term, but not Perioperative Survival after Abdominal Aortic Aneurysm Repair
概述:The neck of a juxtarenal aneurysm is often too short for stable hemostatic stent-graft implantation. Fenestrations (holes) in the stent-graft permit implantation at a more favorable level by providing a route for flow to the renal arteries. In cases of pararenal and thoracoabdominal aortic aneurysm, the aorta around the renal and visceral arteries is too dilated for hemostatic contact with the wall of the stent-graft. There is a gap, which must be bridged by a branch of the stent-graft. In ...

Aortic aneurysm is a weak area in the aorta, the main blood vessel in the body that carries blood from the heart to the rest of the body. As blood flows through the aorta, the weak area bulges and grows over time. This bulging may eventually rupture. Aortic aneurysm in the abdominal region of the aorta is referred to as an abdominal aortic aneurysm (AAA). An aortic stent graft placement is a minimally invasive procedure in which a stent graft is placed inside the aneurysm, creating new walls over the weak spot in the vessels. This graft redirects blood flow to stop the pressure on the weak vessel wall to prevent rupture.. ...
BACKGROUND: The chimney technique has been successfully used to treat juxtarenal aortic aneurysms. The two main issues with this technique are gutter formation and chimney graft (CG) compression, which induce a risk for type Ia endoleaks and stent thrombosis, respectively. In this benchtop study, the geometry and renal artery flow of chimney endovascular aneurysm repair configurations were compared with chimney configurations with endovascular aneurysm sealing (ch-EVAS). METHODS: Seven flow phantoms were constructed, including one control and six chimney endovascular aneurysm repairs (Endurant [Medtronic Inc, Minneapolis, Minn] and AFX [Endologix Inc, Irvine, Calif]) or ch-EVAS (Nellix, Endologix) configurations, combined with either balloon-expandable or self-expanding CGs with an intended higher positioning of the right CG in comparison to the left CG ...

FLAGSTAFF, Ariz. (JANUARY 3, 2018) - W. L. Gore & Associates, Inc. (Gore) today announced the first implant of the GORE® EXCLUDER® Conformable AAA Endoprosthesis in the United States. The successful procedure took place on December 19, 2017 at Maimonides Medical Center in New York by Robert Rhee, MD, Chief of Vascular and Endovascular Surgery, and National Principal Investigator.. This EVAR device, which is the first to feature angulation control, is part of an investigational clinical study approved by the U.S. Food and Drug Administration (FDA). The clinical study will assess the safety and effectiveness of the device in treating infrarenal abdominal aortic aneurysms (AAA) in patients with challenging anatomy. The clinical study consists of two sub-studies, each assessing the device for a different range of patient anatomies. The implantation by Dr. Rhee is part of the short neck sub-study to assess the device in aortic neck angles of 0 to 60 degrees and aortic neck lengths of 10 mm or ...
